Abstract

The invention discloses a railway freight car number identification snapshot method and system. The problems that in the prior art, operation is complex, accuracy and confidence are not high, and the problems are likely to occur are solved. According to the method, a deep neural network is used for detecting a carriage number area and a digital area, and position information, categories and confidence coefficients of the carriage number area and positions, categories and confidence coefficients of the digital area are obtained; and aiming at the identified digital license plate number arrangement, a matching mode based on confidence and Euclidean distance is carried out by utilizing a Hungary algorithm. The operation is more convenient, the accuracy and confidence are high, and the phenomenon of false identification is avoided.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a method and system for identifying and capturing railway freight car numbers. Background technique [0002] Freight railway transportation accounts for more than 70% of my country's domestic freight transportation turnover, so the railway transportation department has a strong monitoring demand for the loading content and loading sequence of freight train cars. In the practice of railway transportation, due to some special reasons, the originally planned carriages may be loaded with other goods, or there may be under-loading or missing loading, which will bring direct or indirect economic losses to the shipping unit. Therefore, it is necessary to arrange for workers to manually verify and record the carriage number and cargo loading of the freight train. The length of a general freight train is about 800 meters to 1000 meters. A single manual inspection takes between h...
